I mean, when you say that "women (in general) are attracted to [X]," since youre ralking about half of the world's population, that's a pretty extraordinary claim and requires extraordinary evidence to support it.
I guess it's more like a working hypothesis, based on the (circumstantial and anecdotal) evidence that I've collected so far. It's by no means enough evidence, so I'm open to changing my opinion (given conflicting evidence).
